Have searched hi and lo for this on here so need some help... I'm looking to upgrade a BES-connected handheld OS from 4.0 to 4.1 using just Desktop Manager. I won't be using my carrier's OS either (Verizon). So far so good but for various reasons I'd like to try and do this without needing to reactivate with a new password Now it seems some of you have done it without having to reactivate afterwards (or it auto reactivated by itself) and some of you have had to wipe the device and reactivate, or at least reactivate with a new password.

Are then any hints for doing this so I don't need to reactivate the devices with new passwords? I read a post after searching that suggested if a handheld has been activated with BES 4.0 before it will recognize the device after the upgrade and carry on as if still activated. Is this true? Have other people found this? Desktop Manager will be able to talk to the BES server if it helps. Does it also need to talk to Exchange? Do I leave the BB plugged in after the upgrade?
